Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)

Bukhari :: Book 5 :: Volume 59 :: Hadith 655

Narrated Ibn 'Abbas:

The delegation of 'Abdul Qais came to the Prophet and said, "O
Allah's Apostle We belong to the tribe of Rabia. The infidels of
Mudar tribe intervened between us and you so that we cannot come to
you except in the Sacred Months, so please order us some things we
may act on and invite those left behind to act on. The Prophet
said, "I order you to observe four things and forbid you from four
things: (I order you) to believe in Allah, i.e. to testify that
None has the right to be worshipped except Allah." The Prophet
pointed with finger indicating one and added, "To offer prayers
perfectly: to give Zakat, and to give one-fifth of the booty you
win (for Allah's Sake). I forbid you to use Ad-Dubba', An-Naquir,
Al-Hantam and Al-Muzaffat, (Utensils used for preparing alcoholic
liquors and drinks)
